Doon-HINGE.

. Specification of Letters Patent. rPatented Sept. 20, 1921.

Application led December 17, 1920.. Serial No. 431,340.

To all whom 'it may concern:

Be it known that I, PAUL PERssoN, a citizen of the United States of America, and resident of Chicago, Cook county, Illinois, have invented a certain new and useful Improvement in Door-Hinges, of which the following isa specification.

This invention relates to an improved door hinge particularly adapted for use with concrete receptacles.

The particular feature of my invention is the provision of an improved hinge for the covers of the receptacle, this hinge being very simple and durable in construction and holding the covers firmly and securely in place.

Referring to the accompanying drawing- Figure 1 is a view in perspective of a receptacle embodying the improvements.

Fig. 2 is a broken away vertical section on line 2-2, Fig. 1.

Fig. 3 is a similar view, showing parts in their opposite position.

The walls of the receptacle A vare composed of waterproof concrete or other cementitious composition and are of some considerable thickness to better resist atmospheric changes and thereby prevent too rapid detorioration of the contents, which is one of the advantages as will be explained further along. Ordinarily the receptacle will be square in horizontal section from the base up to the line 4 and then slopes inward to the contracted flat top 5 having an inlet opening 6 therein which is closed by a hinged cover 7, shown in Fig. 1. y

The receptacle may be located in any convenient place, but will usually be set in the fence at the back end of the premises or building lot with the side 8 facing the alley so that convenient access may be had for the purpose of removing the contents; The side 8 is provided with an outlet opening 9 surrounded by a raised breast curbingr 10 presentingA an inclined surface 11. The opening 9 is closed by a door 12 bearing ao'ainst the inclined surface 11, as shown in Figs. 1 and 2. A hinged rod 13 extends across the upper end of the door and has its respective ends bent downward to provide companion lugs 14 in rigidly securing said door and rod together. The hinge rod is provided adjacent to its respective ends Vwith a kink or twist l5 Which will have a slight binding effect in holding the door in its upturned open position shown in Fig. 3, but will readily yield to a slight pressure in returning the same to the inclined closed position, shown in Figs, 1 and 2. By having the door 12 shut lagainst the inclined surface of curbing 10, it will always remain automatically closed without requiring addltlonal fastening means. Companion eye bolts 16 and 17 are inserted through the walls of the receptacle and are rigidlyheld in place by nuts 18 having a threaded en-A gagement with the inner ends thereof. The outer 'ends of these bolts-are provided with eye-loops 19 loosely engaging hinge-rod 13 and .forms the hinge connection for the openlng and closing movement of door 12. The corners of the free end of the door are turned up to provide lips 20 for the insertion of the end of a shovel or other implement in conveniently raising the same to its open position. A flat bar 21 is loosely mounted on the outer ends of eye-bolts 16 and 17 and is interposed between the eyeloops 19 and the adjacent wall surface and serves to prevent the eye-loops from binding on the hinge rod 13 when the nuts 18 are set up tight and thereby prevent free l action ofthe door-hinge connection.

The `features of the hinge-cover connection 7, are the same as that of'door 12, the same reference characters being used on similar parts shown. By this arrangement the door and cover of the receptacle cannot be carried away or misplaced.

Having thus described my invention, what I claim is 7A hinge construction for attaching a door to arecepta'clev consisting of a flat bar engaging the face of said receptacle adjacent to said door, companion I-bolts passing through said bar and through the wall of said receptacle and being held in place by means engaging the inner face of the receptacle, the eye of said bolts engaging against said bar, a hinged rod extending parallel to the upper edge and substantially the full width of saidl door and passing loosely through said I-bolts and having its ends bent downwardly and secured to -the door.

Signed by me at Chicago, Illinois, this 2 day of December, 1920.
